BUCKET-CAGE FOR MINING-CARS.

SPECIFICATION forming part of Letters Patent No. 625,035, dated May 1e, l1899.

Application filed March l, 1899.

To (LZZ whom, t may concern.-

Be it known that I, WILLIS KNAPP, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented a new and useful Bucket- Cage for Mining-Cars, of which the following is a specification.

The invention relates to improvements in apparatus for handling buckets in removing ore, waste, rock, and earth from a mine.

The object of the present invention is to provide a simple, inexpensive, and efficient device adapted to save time, labor, and expense in removing ore, waste, rock, earth, or analogous material from a mine and capable of effectually-preventing the material from falling from the bucket and the danger incident thereto.

Another object of the invention isto avoid the Wear and tear incident to the rough handling of buckets and to enable the bucket to be readily tilted in any direction to dischargeits contents.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended. u

In the drawings, Figure l is a perspective view illustrating the application of the invention and showing the mining-car with its cage, the bucket being attached. to the hoisting-rope. Fig. 2 is a-perspective view, the bucket being arranged within the cage. Fig. 3 is a vertical sectional view of the same. Fig. i is a detail perspective view of the cage, showing the same removed from its pivoted support. Fig. 5 is a similar view of the pivoted support.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

l designatesa metal cage pivotally mounted on a movable support 2 and arranged on a mining-car 3 and conforming to the conguration of and adapted to receive a bucket 4., whereby the latter may be conveyed from over the shaft to the place where the material is dumped without liability of spilling Serial No. 707,312. (No model.)

anyT of the contents of the bucket and injuring perso-ns in the mine, The cage is composed of upper and lower rings or bands' and 6 and continuous strips of metall connecting the rings and forming the bottom and sides of the cage andthe bars or strips. The bottom portions of the bars or strips are crossed and welded or otherwise secured, so that their upper faces Will be substantially in the same-horizontal plane, and the side portions of the bars or strips, which are secured to the upper and lower rings or bands, have their upper ends arranged substantially flush with the inner face of the upper ring. The lower band or ring is preferably constructed of fiat metal, as shown, and the upper one is constructed of round metal, and it forms a pintle for a swinging hook 7; but the upper ring may be of any other desired construction. The hook 7 is adapted to engage the upper edge of the bucket, and it will retain the latter in thecage while it is being dumped to discharge its contents.

The pivoted support, which is mounted upon the car 3, is secured to the same by a vertical bolt 8, and it is composed of a horizontal bottom portion or bolster` and upwardly-extending arms or standards 9, 1ocated at opposite sides of the car and pivoted at their upper ends to the cage, which is provided with perforated ears lO. The perforated ears 10, which consist of straps of metal, are located on the outer faces of the adjacent side pieces of the cage and are spaced therefrom to receive the upper ends of the arms or clined braces is provided at each side of the pivoted support, which is pivoted by the vertical bolt 8 and is adapted to rotate on the car to arrange the cage for dumping at either side thereof or at either c nd, so that the contents of the bucket may be readily discharged at the desired point. The horizontal pivots 11, which secure the cage to the support, permit the cage to be tilted t0 invert the bucket for dumping the same, and the said cage is maintained in an upright position by a locking device 13,consisting of a substantially U -shaped piece forming a pair of arms and a transverse connecting portion which is arranged in an eye 14 of one of the arms or standards of the movable support, the device being adapted to be swung inward and outward to engage and release the cage. When the device is swung inward, its arms project beyond the adjacent standard and confine the cage by receiving the adjacent side bar thereof between them.

The car and the cage are adapted to be run over the top of the shaft of a mine after the bucket has been hoisted by a rope orcable 15, which passes over a pulley 16 of a gallowsframe 17, and the top of the shaft is covered bya pair of upwardly-opening trap-doors 1S, carrying a section 19 of the track and adapted to be arranged in a horizontal position to complete the track, so that the car may be arranged to receive the bucket,which is lowered into the cage. The bucket after being detached from the hoisting mechanism is secured within the cage by the Jfastening device at the top thereof, and the car can then be readily run to the pla-ce where the material is to be dumped. The pivoted support, which is adapted to be rotated on' the car, may be turned to permit the cage to be tilted toward either side or end thereof. After the bucket has been emptied the car is run back over the shaft to permit the bucket to be attached to the hoisting mechanism, which lowers it down the shaft for the reception of another charge.

The invention has the following advantages: The cage, which is simple and comparatively inexpensive in construction, possesses great strength and durability and is adapted to receive a bucket and convey the same from the shaft to the place of dumping without liability of spilling any of the contents, and all danger to the Workmen resulting from material falling down the shaft of a mine is avoided. The wear and tear on buckets resulting from roughly handling and dumping the same on the ground are obviated and a great saving of time and labor is effected.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

What is claimed isl. A device of the class described comprising a car, a support mounted on the car and having a vertical pivot, and a bucket-receiving cage mounted upon the support and arranged to be tilted to discharge the contents of a bucket, substantially as and for the purpose described.

2. A device of the class described comprising a support designed to be mounted on a car and arranged to rotate on a Vertical axis, and a tilting bucket-receiving cage carried by the support, whereby the contents of a bucket may be discharged in any direction, substantially as described.

3. A device of the class described, comprisl ing a support designed to be mounted on a car and arranged to rotate on a vertical axis, said support being provided at opposite sides with standards or arms, a bucket-receiving cage pivotally mounted between the standards or arms and adapted to tilt to discharge the contents of a bucket, and locking devices for holding the cage in an upright position and for securing a bucket in the same, substantially as described.

4. A device of the class described comprising a pivoted support designed to be mounted on a car and arranged to rotate on a vertical axis and composed of a horizontal portion or bolster, vertical arms or standards, and braces connecting the arms or standards and the bolster portion, a bucket-receiving cage pivoted between the arms or standards, and a locking device hinged to one of the arms or standards, arranged to be supported by the adjacent brace and adapted to engage the cage, substantially as described.

5. A device of the class described comprising a pivoted support designed to be mounted on a car, and a cage carried by the support, adapted to receive a bucket and comprising upper and lower rings or bands, and the connecting strips or bars secured to the rings or bands and forming the sides and bottom of the cage, substantially as described.

6. A device of the class described comprising a support designed to be mounted on a car and provided with opposite standards, braces supportin gv the standards,a cage adapted to receive a bucket and pivotally mounted between the standards, and a substantially U-shaped locking device hinged to one of the standards and provided with arms arranged to engage the cage and supported in its engaging position by the adjacent brace, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
